 You need to shorten the string to be under the length limit, while keeping as much detail as possible. The result may NOT be longer than the length limit.
 based on that, please reply only the shortened string. Give me 5 choices. if the length is too long, discard the string and try another one.Return the data as a python list containing the result as {"shortened_string": shortened_string, "length": lengthasInt}. Do not return the answer in a codeblock, use a pure  string. Before answering, check the results and if ANY is longer than the needed_length, discard all and try again""",
